Questions

Is there a KiCad symbol and footprint for the HX7544?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1GND_2IN_3OUT and the footprint Package_TO_SOT_SMD:SOT-89-3, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the HX7544?

SOT-89-3, with 3 pins. Its footprint is drawn on this page.

Where is the HX7544 datasheet?

HX publishes it: the Datasheet link on this page opens it.

Where can I order the HX7544?

JLCPCB lists it as part C296149, with 1,163 in stock; the sellers' links on this page open their listings.

What can replace the HX7544?

Parts like it in the library: the HT7544-1 by UMW, the HT7144-1 by MSKSEMI, the H7544-1 by Shanghai Siproin Microelectronics and the HT7544-1 by TDSEMIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
